Method and apparatus for providing broadcasting service

Abstract

A method for providing a broadcasting service containing contents includes: generating contents representations metadata for describing possible representations of the contents; and outputting the contents representations metadata, wherein the contents representations metadata includes one or more contents representations description elements which describe a metadata tool defined by a standard specification.

1 . A method for providing a broadcasting service containing contents, the method comprising:
 generating contents representations metadata for describing possible representations of the contents; and   outputting the contents representations metadata,   wherein the contents representations metadata comprises one or more contents representations description elements which describe a metadata tool defined by a standard specification.   
     
     
         2 . The method of  claim 1 , wherein the metadata tool comprises at least one of VariationSet defined in MPEG-7, AdaptationQoS defined in MPEG-21, and CrossConversionQoS defined in MPEG-21. 
     
     
         3 . The method of  claim 1 , wherein the contents representations metadata further comprises an URI element which references to a description of contents representation existing outside the contents representations metadata. 
     
     
         4 . A method for providing a broadcasting service containing contents from a service provider to a user, the method comprising:
 generating an adaptation capabilities metadata for describing contents adaptation capabilities of the service provider; and   outputting the adaptation capabilities metadata,   wherein the adaptation capabilities metadata comprises at least one of a transmutation capability element, an adjustment capability element, a translation capability element, and an addition capability element.   
     
     
         5 . The method of  claim 4 , wherein the transmutation capability element comprises a delay example element which describes a delay example of a transmutation method described in the transmutation capability element. 
     
     
         6 . The method of  claim 4 , wherein the transmutation capability element comprises an original format element and a destination format element. 
     
     
         7 . The method of  claim 4 , wherein the adjustment capability element comprises contents format element and a conversion method element. 
     
     
         8 . The method of  claim 4 , wherein the translation capability element comprises an original language element, a destination language element, and a language format element. 
     
     
         9 . The method of  claim 4 , wherein the addition capability element comprises a holder format element, an added object element, an added object format element, and an added operation element. 
     
     
         10 . An apparatus for providing a broadcasting service containing contents, the apparatus comprising:
 a metadata generation unit configured to generate contents representations metadata for describing possible representations of the contents; and   an output unit configured to output the contents representations metadata,   wherein the contents representations metadata comprises one or more contents representations description elements which describe a metadata tool defined by a standard specification.   
     
     
         11 . An apparatus for providing a broadcasting service containing contents from a service provider to a user, the apparatus comprising:
 a metadata generation unit configured to generate an adaptation capabilities metadata for describing contents adaptation capabilities of the service provider; and   an output unit configured to output the adaptation capabilities metadata, wherein the adaptation capabilities metadata comprises at least one of a transmutation capability element, an adjustment capability element, a translation capability element, and an addition capability element.   
     
     
         12 . A method for consuming a broadcasting service containing contents, the method comprising:
 receiving contents representations metadata for describing possible representations of the contents; and   selecting contents to be provided to a user by using the contents representations metadata,   wherein the contents representations metadata comprises one or more contents representations description elements which describe a metadata tool defined by a standard specification.   
     
     
         13 . A method for consuming a broadcasting service containing contents, the method comprising:
 receiving an adaptation capabilities metadata for describing contents adaptation capabilities of a service provider; and   selecting contents to be provided to a user by using the adaptation capabilities metadata,   wherein the adaptation capabilities metadata comprises at least one of a transmutation capability element, an adjustment capability element, a translation capability element, and an addition capability element.   
     
     
         14 . An apparatus for consuming a broadcasting service containing contents, the apparatus comprising:
 an input unit configured to receive contents representations metadata for describing possible representations of the contents; and   a control unit configured to select contents to be provided to a user by using the contents representations metadata,   wherein the contents representations metadata comprises one or more contents representations description elements which describe a metadata tool defined by a standard specification.   
     
     
         15 . An apparatus for consuming a broadcasting service containing contents, the apparatus comprising:
 an input unit configured to receiving an adaptation capabilities metadata for describing contents adaptation capabilities of a service provider; and   a control unit configured to select contents to be provided to a user by using the adaptation capabilities metadata,   wherein the adaptation capabilities metadata comprises at least one of a transmutation capability element, an adjustment capability element, a translation capability element, and an addition capability element.
